DESC: Technical field
The present invention relates to the storage and mixing of liquid containing to different constituents. More specifically to the improved liquid container that stores the powdered constituent/ingredient and water/liquid ingredient in separate compartments wherein they can be mixed and dispensed as required.

Background of invention
The liquids such as milk, fruit juice, protein shakes etc are stored in containers for selling. These liquids stored in such manner however have shorter shelf life due to the continuous degradation with increasing storage time. Various techniques have been utilized to increase the shelf like adding of preservatives which only adds to the use of more chemical constituents that may be harmful for consumer.
Some bottle design have been constructed for the pharmaceutical formulations as in US patent US20070193894A1 wherein the powdered counterpart and liquid formulation are stored in different compartments that are mixed in middle compartment before dispensing.
Also US patent US5419445A describes the baby nipple bottle design that facilitates the mixing of water and milk powder before use which is stored in different compartments before use.
However the prior art fails to suggest the bottle design that can be used for multiple liquid formulations that will prolong their shelf life.

Object of the present invention
The present invention objects to give extended shelf life to milk based drinks, other purposes include adding different types of ingredients (solid or otherwise) to a milk based drink which was not earlier possible without compromising on the shelf life of the milk based drink.
Another object of the invention is to facilitate extended shelf life not just for milk and milk based drinks but also for fruit powder, herbal powder, protein powder etc.
Yet another object of the invention is to boost the export of milk based drinks/beverages from India to western countries, where the existing product cannot fulfill the shelf life requirements due to long transit time & requirement of long enough shelf life after it reaches the destination to be sold.

Summary of the present invention
The present invention pertains to the container/bottle that is constructed to store the liquid constituent and powder constituent of the liquid formulation in different compartments that are mixed before use. Such arrangement or construction of the container prolongs the shelf – life of the milk or any other liquid content.
The present invention serves the purpose of longer use of the liquid constituent as the stability of the ingredients is increased as they are not mixed and remain in the inactive form until constituted together. This not only increases the shelf-life but also keeps the freshness of the liquid content intact during the consumption by the consumer. The present invention mainly is utilized for commercial volume sale wherein the bottle container mechanism is for one time use only.
The bottle in the present invention mainly comprises of four parts that facilitates the storage of the liquid constituent for longer time. These are,base liquid bottle 1, base liquid cap 2, counterpart cum powder storage 3, counterpart cap 4, base seal/plastic string 5.
The counterpart/powder storage 3 is contained within the housing7. The counterpart cap 4 has a plastic seal string 9 attached at its rim which ensures the sealing of the container before use and prevents tampering. The housing 7 contains the counterpart/powder storage 3 that hold the powder constituent that is thus stored in its dried form.The base liquid cap 2 has breakable internal seal 6. The seal is however irreplaceable and is for one time use only. Lower end of the base liquid cap attaches to the upper open end of the base liquid bottle 1. The base seal/plastic string 5 is at the lower end of the housing 7 of the counterpart storage 3 that is to be removed before use.
The material used for making bottle parts is HDP(High density polyethylene) plasticwhich is crack resistance and is immune to leaching which thus protects the food component stored inside from any undesirable reactions. The food grade silicone that is environmental friendly, odorless and non-toxic is used in base liquid cap 2 for complete sealing to avoid any tampering. The invention also makes use of the anticaking agent and nitrogen flushing thus preventing the caking of dry powder component inside the counterpart storage 3.
The invention works with removal of base seal/plastic string 5 before use. After removal of base seal 5, the bottle is pushed from the uppermost end. This causes the breaking of the internal seal 6 of the base liquid bottle cap 2. With breaking of the internal seal 6 the liquid from the counterpart/powder 3 storage falls into the base liquid bottle 1 containing the liquid constituent. The base liquid bottle is then subjected to shaking that facilitates the proper mixing of the liquid and powder constituent that forms the original liquid formulation eg. Mixing of water and milk powder through this process will form the milk which can then be utilized by the consumer in fresh form.

Detail Description of the invention
The liquid food products are stored in the container for sell. The shelf -life of such liquid foods is however limited as the reactivity of the various constituents in the liquid contributes to its fast degradation and thus shorten shelf-life.
The present invention provides the solution to these limitation with facilitating the storage of dry and liquid component of the liquid product in different compartments within the same container. The bottle/container of the invention is constructed such that the two components are mixed just before the consumption. This facilitates the increased stability and low reactivity during storage which thus prolongs the shelf life.
The bottle container of the present invention also uses the high quality material of the food grade silicone which has high dimensional stability and is non-deformable. This also ensures the safe storage of the components for prolong time without any toxic reaction inside the bottle container.
Referring to the FIG 1, it is shown that the present invention includes a base liquid bottle/storage 1 at the lower portion of the bottle container that stores the liquid component 28 like water.The base liquid bottle 1 has a closed end base 9 for standing in an upright position and a slightly reduced diameter neck portion 10 and upper open end 11, upper open end 11 has external connecting threads 12 which attaches to the base liquid cap 2.
The base liquid cap 2 has the upper open end 13 and the slightly enlarged diameter lower open end 14. The lower open end 14 has internal connecting threads 15 that connects with the upper open end 11 of base liquid bottle having external connecting threads 12. The base liquid cap has food grade silicone rubber 16 around the upper open end 13. The base liquid cap has a internal breakable seal 6 positioned between the upper open end 13 and lower open end 14 just above the internal connecting threads 15.
The counterpart storage 3 that stores the dry component 27 of the liquid food product. The counterpart storage 3 has upper open end 17 with external connecting threads 18, a slightly reduced diameter neck portion 8 with lower open end 19. The counterpart storage is inside the housing 7 which has cylindrical walls 20. There is a base string seal 5 at the lower rim 21 of the housing 7.
The counterpart cap 4 has a circular dome- shaped upper close end 22, and a lower open end 23 with internal connecting threads 24 that connects with the external connecting threads 18 of upper open end 17 of counterpart storage 3. The counterpart cap 4 has plastic string seal 25 at the rim 26 of lower open end 23.
Referring FIG 2, The counterpart cap 4 closes the counterpart storage 3 with the internal connecting threads 24 at its lower open end 23 connecting with the external connecting threads 18 of the upper open end 17 of the counterpart storage 3. The plastic string seal 25 seals the counter cap 4 with the counterpart storage 3 to prevent any tampering.
The counterpart storage 3 stores the dry component of the liquid product. The dry component is nitrogen flushed and treated with anticaking agent before filling it inside the counterpart storage 3 to avoid any caking of the powder inside the storage. The lower open end 19 of the counterpart storage 3 fixes inside the upper open end 13 close to the internal breakable seal 6 of the base liquid cap 2. The internal seal 6 is made up of fine HDP plastic that do not form any plastic particles after breaking.
The upper open end 11 of the base liquid bottle 1 has external connecting threads 12 that attaches with the internal connecting threads 15 of the lower end 14 of the base liquid cap 2. The housing 7 of the counterpart storage 3 with base string seal 5 at its lower rim 21 fixes over the neck portion 10 of the base liquid bottle 1. The base liquid bottle 1 stores the liquid component of the liquid food product.
Referring FIG 3, the dry component 27 inside the counterpart storage 3 an the liquid component 28 inside the base liquid bottle are separated by the base liquid cap 2 with its lower open end 19 placed close to the internal seal 6 of the base cap 2. The base liquid bottle is fitted inside the lower end 14 of the base cap 2 by connecting with the internal threading 15. The dry component is filled inside the counterpart storage 3 by removing the counterpart cap 4 from the upper end of the counterpart storage by rotating the counterpart cap 4 in anti-clockwise direction thus forcing it out from the threaded connection with the counterpart storage 3.After the dry component is filled and the counterpart cap 4 is replaced on the counterpart storage 3, the connection is sealed with the plastic string seal 25 at the rim 26 of lower open end 23 of counterpart cap 4 to prevent any tampering with the dry component during handling and transport of the liquid bottle counter.
The liquid bottle container is of one time use and is mainly used for commercial purpose wherein the bottle used for consumer foods like milk, fruit juice, protein shake etc. which will be maintained in the fresh and stable state.
For the use of liquid bottle container, first, the base string seal 5 is removed. This facilitates the downward displacement of the counterpart storage 3 contained within a housing 7. The liquid bottle is pushed from the uppermost end i.e dome-shaped upper close end 22 of counterpart cap 4. This push causes the lower end 19 of the counterpart storage 3 to break the internal seal 6 of the base cap 2, pushing it to one side preventing its complete detachment and falling into the liquid below inside the base liquid bottle 1. This facilitates the dropping of the dry component from the counterpart storage 3 into the liquid component inside the base liquid bottle 1 causing the mixing of the two components and forming the required liquid formulation. The bottle container is shaked well to mix the two components properly. E.g. milk powder from counterpart storage 3dropping into the water inside the base liquid bottle 1 will lead to formation of milk with more stability and fresh taste.
Thus the bottle container according to the invention can be used to maintain the constituents of a liquid formulation in an active or stable form until they are required for use, thereby extending their shelf life.
